Newbie tire/wheel question

Ok, I feel like I have to be over thinking this. Right now, my '15 Sport, has the stock 16" steelies. This leaves a LOT of space between the tires and the body. My really dumb question is this. If I go with bigger tires, maybe wheels too, will it actually raise my Jeep by the difference between old and new, or will it simply fill in some of the space between tire and body... and maybe only raise it a little? The reason I'm worried about raising the Jeep is because the entrance to my garage doesn't leave much room for me to go any higher.

I'm sure the answer is obvious to most, but not to this beginner. Thanks!

Any 33 tire will be close to the height of the OEM set up, which is about 32-32.5”. And most 35’s are around 34”. So your talking an additional 2” at the most. I’d measure your current tire height now as it sits. Then measure the top of your Jeep to the top of the garage opening and see how much room you have to play with. Your current tire size would be nice to know and what size tire and wheel you want to go to.

Also donít forget it is actually half the difference so going from 32Ē to 34Ē is only a one inch gain in height

@bgriff008 and @PlineyTheElder Thanks for the replies.

So my current tires are 225/75R16 which are approx 29".

If I threw on some 255/75R17 which I believe are 32", that would mean an added 1.5 inches?

Yep that is correct.

I suppose you could consider the ply of the side wall etc for how much the tire squishes. The best measurement would be under load with the Jeep sitting on it.

As you point out not all tires are the same size as described such as BFGs apparently run smaller than advertised too so you can factor that in as well.
